What File Format Should I Use for Printing Discount Cards?
Wondering which file format to use for printing discount cards? Learn the best formats like PDF, AI, or EPS to ensure sharp, high-quality results.

When you're ready to print your discount cards, there's one thing that can make or break the final product: the file format. You could have a great design, but if you choose the wrong file, it can ruin everything. The wrong format might lead to blurry images, misaligned text, or colors that don’t match what you expected. Whether you're creating cards for a special promotion or your business, getting the format right ensures your cards look professional and clean.
The Importance of Choosing the Right File Format
Choosing the right file format isn't just about making things easier for your printing company. It’s about making sure your custom discount cards come out looking professional and error-free. From pixelated logos to unreadable text, a poor file choice can ruin the appearance of your discount cards and ultimately harm your brand image.
Common File Formats for Printing Discount Cards
There are several file formats available for printing plastic discount cards, but some are more suitable than others. Here's a quick rundown of the most commonly used formats:
1. PDF (Portable Document Format)
PDF is by far the most popular format when it comes to print discount cards. It's widely accepted by most print shops and offers several advantages:
-
Lossless quality: PDF files retain all the details of your design without losing any resolution.
-
Color accuracy: PDFs maintain accurate colors, which is crucial when dealing with designs for custom discount cards.
-
Embedded fonts: This ensures that the text on your card will display as intended, even if the print shop doesn’t have the exact fonts on their system.
Why it works:
When you’re designing your plastic discount cards, the last thing you want is for the design to change after it's printed. PDFs are ideal because they keep everything consistent, from the layout to the text. Plus, they’re easy to share with the printer without worrying about missing elements.
2. AI (Adobe Illustrator)
If you're using Adobe Illustrator for your design, you may want to use an AI file for your custom discount cards. Adobe Illustrator’s native file format is ideal for vector designs and complex artwork. The advantages include:
-
Scalable artwork: AI files are vector-based, meaning they can be resized without any loss of quality. This is crucial if you need to scale your design up or down.
-
Editable files: You can easily edit the file if you need to make changes before printing.
Why it works:
For intricate designs, especially those involving logos or detailed illustrations, AI offers the flexibility and quality needed for high-resolution prints.
3. EPS (Encapsulated PostScript)
Another vector-based file format, EPS is a strong contender when it comes to plastic discount cards. It’s a versatile format used by graphic designers for professional-grade artwork.
-
High-quality vector graphics: Like AI files, EPS files can be scaled without losing quality.
-
Compatibility: Most printing companies can work with EPS files, and they are compatible with many design programs.
Why it works:
If you want to maintain the highest quality for your print discount cards and your design includes complex vector art, EPS is a good option. It ensures your designs remain crisp and clear at any size.
4. PNG (Portable Network Graphics)
Although PNG files are typically used for digital designs, they’re sometimes used in printing as well, especially when transparency is needed.
-
Transparent background: One of the biggest benefits of a PNG file is its ability to maintain transparency. This is useful if your plastic discount cards have a transparent background or if you need logos with no white boxes around them.
-
Good for simple designs: While PNG is perfect for logos and images with transparent backgrounds, it may not be the best choice for full-scale card designs or text-heavy designs.
Why it works:
If your custom discount cards involve a simple logo or design that requires transparency, PNG is the way to go. However, it's important to make sure the resolution is high enough to avoid blurry prints.
5. JPG/JPEG (Joint Photographic Experts Group)
JPG files are commonly used in photography and can sometimes be used for print discount cards, but they come with some limitations:
-
Lossy compression: JPG files lose some of their quality when saved, which can result in pixelated or blurry images when printed.
-
Best for photographs: If your design includes photographs and the file size is too large, JPG is a good option.
Why it works:
JPG files can work if you're printing images that don’t require fine detail, like photographs on your plastic discount cards. But be cautious, as JPGs may not be the best choice for logos or text-heavy designs.
Key Considerations for Choosing Your File Format
Now that you know the top file formats for plastic discount cards, there are a few additional things to keep in mind when preparing your design files for printing.
Resolution Matters
No matter what file format you use, resolution is critical. For print, you need a resolution of at least 300 DPI (dots per inch) to ensure your images and text appear crisp and clear. Low-resolution images can result in blurry or pixelated cards that give off a cheap, unprofessional look.
-
Vector formats (AI, EPS): These file types are resolution-independent, meaning they can scale to any size without losing quality.
-
Raster formats (JPG, PNG): Ensure these files are at least 300 DPI at the actual print size.
Color Mode
Printing is done in CMYK (Cyan, Magenta, Yellow, Key/Black) color mode, so make sure your design is created in CMYK rather than RGB (Red, Green, Blue), which is used for screens. Colors may look different on screen than they do when printed if they’re not adjusted properly.
-
PDF, AI, and EPS: These formats allow for easy color adjustments in CMYK mode.
-
JPG and PNG: These formats should be converted to CMYK before printing to ensure accurate color reproduction.
Common Printing Issues to Avoid
Even with the right file format, printing plastic discount cards can still go awry if you don’t pay attention to a few key details:
1. Missing Fonts
When using text in your design, make sure that your fonts are either embedded in the file (like in a PDF) or outlined (in AI or EPS files). This will prevent issues where the printer doesn’t have the same fonts and the text is altered.
2. Bleed and Margins
Ensure that your design includes a bleed area (usually an extra 0.125 inches on each edge) to account for any trimming during the printing process. If your design goes to the edge of the card, this is especially important.
3. Low-Resolution Images
Avoid using low-resolution images in your design. This will cause them to appear blurry or pixelated when printed, especially if they are resized. Stick to high-quality, 300 DPI images to ensure a sharp result.
Which File Format Should You Choose?
When it comes down to it, PDF files are often the best choice for plastic discount cards because of their versatility, quality retention, and compatibility. However, if you’re working with vector graphics and want maximum flexibility, AI or EPS formats are great options. Just remember that JPG and PNG are better suited for images and simpler designs, so they should only be used when appropriate.
Ultimately, the choice of file format will depend on the complexity of your design, the type of discount card you're creating, and your printer's specifications. By keeping these considerations in mind, you can ensure that your custom discount cards come out looking exactly how you envisioned them.

FAQs
What is the best file format for printing discount cards?
The most recommended file format for printing discount cards is PDF. It preserves the quality of vector graphics and ensures that fonts and images appear as intended. Additionally, PDFs are widely accepted by most printing companies and are compatible with various design software.
Can I use a JPG or PNG file for printing discount cards?
While JPG and PNG files can be used, they are not ideal for printing discount cards. These formats are raster-based and may lose quality when resized. They are better suited for digital use rather than high-quality printing.
What is the difference between vector and raster file formats?
Vector file formats (like AI, EPS, and PDF) use mathematical equations to create graphics, allowing them to be scaled without losing quality. Raster file formats (like JPG and PNG) are made up of pixels and can become pixelated when resized. For printing discount cards, vector formats are preferred for their scalability and clarity.
